## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2215, "days_push": 1586, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated collection of Java learning notes and articles covering advanced topics such as microservices, middleware, caching, database optimization, search engines, and distributed systems. Content is organized as a knowledge map with links to in-depth write-ups on Spring, Spring Boot, Spring Cloud, MyBatis, MySQL, Elasticsearch, ZooKeeper, and design patterns.

## Use cases
- learn advanced java concepts
- prepare for java backend interviews
- understand spring cloud microservices
- study mysql optimization techniques
- learn how message queues and caching work
- review common design patterns with examples
- find a java learning roadmap

## When to choose
- you are a Java developer seeking structured advanced-level study material
- you want article-style explanations of Spring ecosystem, middleware, and distributed systems
- you are preparing for Java backend interviews

## When to avoid
- you need runnable production code or a maintained library
- you want non-Java or beginner-level tutorials
- you need officially documented or version-pinned reference material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: tutorials, backend, developer-tools, databases
- platform: jvm
- tags: java, spring, springboot, microservices, middleware, caching, mysql, elasticsearch, zookeeper, design-patterns, distributed-systems, interview-prep, chinese, search
